Building Blocks
The service that a particular type of traffic receives is determined by
assigning a QoS profile to a traffic grouping or classification. The
building blocks are defined as follows:
❑ QoS profile — Defines bandwidth and prioritization
parameters.
❑ Traffic grouping — A method of classifying or grouping
traffic that has one or more attributes in common.
❑ QoS policy — The combination that results from assigning a
QoS profile to a traffic grouping.
QoS profiles are assigned to traffic groupings to modify switch
forwarding behavior. When assigned to a traffic grouping, the
combination of the traffic grouping and the QoS profile comprise an
example of a single policy that is part of Policy-Based QoS.
The next sections describe how QoS profiles are used and modified.
After this, various traffic groupings are explained and QoS profiles
are assigned to the traffic groupings.
